Poor service

<p>So, I have a top up contract with MTN, I should've had two upgraded new phones by now the firs new phone I should have recieved in 2014 the second one in2016 but the phone's I wanted at the branch I went to were not on display and I couldn't purchase a phone I have never seen. Yesterday MTN blocked my number so I can not purchase any airtime or data, I'm exactly sure why and how exactly I owe money on the TOP up contract I use because payments are debited every month. I tried calling customer car for over an hour using my phone and a vodacom number. I finally got through using the Vodacom and spoke to a consultant by the name of Zinhle who gave me a technical assistance number that's not working she was at the prepaid switchboard and couldn't assist but the contract customer care number I called did not have to a "speak to a consultant option"...So I'm sitting with an old phone, (I've paid for two phone upgrades already) that doesn't allow me to make outgoing calls because my account is in arrea apparently and I'm not exactly sure how that's possible because payments were made... I can't get through to customer care and God know's emails are only responded to after 5 days... </p>
